2 Introduction
The IFX-P200 is a hand-held, battery operated ultrasonic flowmeter employ-
ing clamp-on sensors for the measurement of liquids in full, enclosed pipes.
Flow measurements can be undertaken without interruption of the process
or interference with the integrity of the pipeline. The clamp-on sensors are
attached to the outside of the pipes. The IFX-P200 uses ultrasonic signals
for measurement of the flow, employing the transit-time method.
Ultrasonic signals are emitted by a transducer installed on a pipe and re-
ceived by a second transducer. These signals are emitted alternately in the
direction of flow and against it. Because the medium is flowing, the transit
time of the sound signals propagating in the direction of flow is shorter than
the transit time of the signal propagating against the direction of flow. The
transit-time difference ΔT is measured and allows the determination of the
average flow velocity along the path of acoustic propagation. A profile cor-
rection is then performed to obtain the average flow velocity over the cross-
sectional area of the pipe, which is proportional to the volumetric flow rate.

3.2 Clamp-on sensor installation
The correct selection of the sensor location is crucial for achieving reliable
measurements and a high accuracy. Measurement must take place on a
pipe in which sound can propagate (see Acoustic Propagation) and in which
a rotationally symmetrical flow profile is fully developed (see Straight Pipe
Lengths).
The correct positioning of the transducers is an essential condition for error-
free measurements. It guarantees that the sound signal will be received un-
der optimal conditions and evaluated correctly. Because of the variety of ap-
plications and the different factors influencing the measurement, there can
be no standard solution for the positioning of the transducers.
The correct position of the transducers will be influenced by the following
factors:
●diameter, material, lining, wall thickness and general condition of the
pipe;
●the medium flowing in the pipe;
●and the presence of gas bubbles and solid particles in the medium.
Check that the temperature at the selected location is within the operating
temperature range of the transducers (see technical specification in the Ap-
pendix).
Acoustic propagation is achieved when the flowmeter is able to receive suf-
ficient signal from the transmitted ultrasonic pulses. The signals are attenu-
ated in the pipe material, the medium and at each of the interfaces and re-
flections. External and internal pipe corrosion, solid particles and gas con-
tent in the medium do heavily contribute to signal attenuation.
Sufficient straight lengths of pipe on the inlet and outlet of the measuring
location guarantee an axi-symmetrical flow profile in the pipe for good meas-
urement accuracy. If no sufficient straight lengths of pipe are available for
your application, measurements are still obtainable but the uncertainty of the
measurement can be compromised.

3.3 Installation location
Select an installation location following the recommendations in Table 1 and
try to avoid measuring:
●in the vicinity of deformations and defects of the pipe,
●near welding seams,
●where deposits could be building up in the pipe.
For a horizontal pipe:
Select a location where the transducers can be mounted on the side of the pipe, so that the sound waves emitted by the
transducers propagate horizontally in the pipe. In this way, the solid particles deposited on the bottom of the pipe and
the gas pockets developing at the top will not influence the propagation of the signal.

Incorrect
For a free inlet or outlet pipe section:
Select the measuring point at a location where the pipe cannot run empty.

mended distances from disturbance sources.

3.4 Pipe preparation
●Clean dirt and dust from around the area of the pipework where the
sensors are to be placed;
●Remove loose paint and rust with a wire brush or file.
Firmly bonded paint does not necessarily need to be removed provided the
flowmeter diagnostics indicate sufficient signal strength.
3.5 Clamp-on sensor mounting configurations and
distance
The most common clamp-on sensor mounting configuration is the Reflection
Mode, sometimes known as V-Mode (see Illustration 3, sketch (1). Here, the
ultrasonic signal passes twice through the medium (2 signal passes). The
Reflection Mode is the most convenient mounting method as the transducer
separation distance can be measured easily and the sensors can be accu-
rately aligned. This method should be used whenever possible.
An alternative mounting configuration (Illustration 3, sketch (3)) is the Diag-
onal mode (Z-Mode). The signals travel only once through the pipe. This
method is often used for larger pipes where greater signal attenuation might
occur.
Further variation of the Reflection and the Diagonal Modes are possible by
altering the number of passes through the pipe. Any even number of passes
will require mounting the sensors on the same side of the pipe, while with an
odd number of passes, the sensors must be mounted on opposite sides of
the pipe. Commonly, for very small pipes, sensor mounting configurations
such as 4 passes (W-mode) or 3 passes (N-mode) are used (Illustration 3,
sketch (2)).

Hand-held_Flow_Meter_IFX-P200_EN_2017_July_Rev.01
The transducer separation distance A is measured from the inside edges of
the sensor heads as shown in illustration 3. It is automatically calculated by
the flowmeter based on the parameter entries for pipe outside diameter, wall
thickness, lining material and thickness, medium, process temperature, the
sensor type and the selected number of signal passes.
A negative separation distance A < 0 can occur for mounting configurations
on small pipes where diagonal mode operation has been selected (see Illus-
tration 3, sketch (3). Negative separation distances may be suggested for
reflection mode installations, but are not possible. In these cases, use diag-
onal mode or a larger number of passes.

3.7 Clamp-on sensor mounting
Before the sensors can be mounted
●the installation location should have been determined,
●a sensor mounting method should be chosen,
●the flowmeter batteries must be sufficiently charged,
●the sensors must be connected to the transmitter.
Depending on which sensor mounting method is being used, the clamp on
sensors are either mounted on the same side of the pipe (Reflection Mode)
or on opposite sides of the pipe (Diagonal Mode – See Section 2.5).
3.7.1 Sensor pipe mounting configurations
3.7.2 Acoustic coupling gel
In order to obtain acoustical contact between the pipe and the sensors, apply
a bead of acoustic coupling gel lengthwise down the centre of the contact
area of the sensors.
3.7.3 Correct positioning of the sensors
Mount the transducer pair so that the front edges of the sensors (opposite
the cable entry) face each other.
Illustration 4: Sensor pipe mounting configurations

There is a different engraving on the top of each transducer. The transducers
are mounted correctly if the engravings on the two transducers form an ar-
row. The transducer cables should point in opposite directions.
Later, the arrow, in conjunction with the indicated measured value, will help
to determine the direction of flow.
The sensor separation distance is automatically calculated by the flowmeter
based on the parameter entries for pipe outside diameter, wall thickness, lin-
ing material and thickness, medium, process temperature, the sensor type
and the selected number of signal passes. The sensor positioning screen
(above, and Section 3.3) allows fine adjustment of the sensor location.
3.7.4 Sensor mounting with fixtures and chains
●Insert the retaining clip into the groove on the top of the transducer
and secure it using the screw knob.
●Apply some acoustic coupling component to the contact surface of
the transducer.
●Place the transducer on the side of the pipe or alternatively up to 45
degrees from the horizontal plane through the pipe.
This is advisable to establish the best acoustic contact since on top
of the pipe air pockets could develop and deposits could accumulate
at the bottom of the pipe.
●Take the spring end of the chain in one hand and insert the last ball
element in the vertical slot of the retaining clip. Mount the chain
around the pipe.
●Pull the chain firmly around the pipe and fasten it in the lateral slot of
the retaining clip. There should be no air pockets between the trans-
ducer surface and the pipe wall.
●Mount the second transducer the same way.
●Using a measuring tape, adjust the sensor separation distance as
suggested by the flowmeter. When the sensor positioning screen
(Section 3.3) is displayed, the middle bar allows fine adjustment of
the sensor location.
